我正在尝试创建一个始终处于横向模式的 LaTeX 包，但尽管使用了\LoadClass[landscape]{article}和\RequirePackage[landscape]{geometry}，我还是遇到了麻烦。我将其归结为以下最小可验证示例：
testlandscape.cls：
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{landscapetest}[forcing landscape mode]
\LoadClass[landscape]{article}
\RequirePackage[landscape]{geometry}
test.tex：
\documentclass{landscapetest}
\begin{document}
landscape mode?
\end{document}
运行pdflatex test.tex不会产生横向 PDF。但是，当我更改test.tex为以下内容时：
\documentclass[landscape]{landscapetest}
\begin{document}
landscape mode?
\end{document}
它做制作横向 PDF。有什么方法可以强制横向模式而不需要我的包的用户指定[landscape]？
这是我的输出pdflatex --version：
